The Redot Team is back with another round of fixes and features. This release wraps up our first quarter of dedicated work on the LTS branch, and it’s packed with enhancements designed to make your experience smoother, faster, and more powerful than ever. This project is run by 100% volunteers. If you’d like what we’re doing and want to help sustain development, please consider donating on https://ko-fi.com/redotengine or a subscription on discord.
About Redot LTS
Redot LTS emphasizes core stability while allowing community-driven enhancements. The Redot team continues regular bug fixes; LTS provides greater room to merge contributor PRs that optimize existing features or introduce new ones without risking breaking changes from upstream merges. Redot LTS is based on Godot 4.5 — contributions that preserve compatibility with Godot 4.5 projects are welcome. We encourage the community to get involved and help shape the engine’s future.
Standout Highlights from This Release
- Patched to Godot 4.5.2 (upcoming release), includes many bug fixes backported from 4.6 by @Arctis-Fireblight
SignalSmith Time Stretching Module
This module introduces a new SignalSmith audio processing module that wraps the Signalsmith Stretch time-stretching library, accompanied by comprehensive third-party audio processing libraries (Signalsmith Linear for FFT/STFT/linear algebra and Signalsmith Stretch for pitch/time manipulation). Includes module registration, build configuration, documentation, and web/command-line utilities for the third-party libraries.
- Added SignalSmith audio processor for independent tempo and pitch control on streaming audio buffers.
- Supports real-time time-stretching (speed changes without pitch alteration) and pitch shifting capabilities.
- Enables configurable sample rate, channel count, tempo adjustment, and pitch transposition.
UID Viewer
UIDs in Godot are unique, persistent identifiers assigned to resources like scenes, textures, or scripts. They let you reference those resources using stable uid:// paths instead of file paths, so renaming or moving files won’t break links across your project.
Until now, there hasn’t been a sane way of accessing them other than rightclicking a file and copying the UIDs, which makes it difficult if you have a lot of files to go through. The UID Viewer solves this by showing a list of UIDs across an entire project. You can Sort, copy and paste, or highlight the file in the Filesystem by doubleclicking on it. You can also see and copy the system links to all the files.
Native Model Context Protocol(MCP)
This PR introduces a native C++ implementation of the Model Context Protocol (MCP) as a first-class engine module. This enables AI coding assistants (OpenCode, Claude, etc.) to interact deeply with Redot projects through a standardized JSON-RPC interface.
Beyond simple file editing, this module provides the AI with “eyes and hands”—allowing it to see the game window, manipulate the live scene tree, and simulate user input for truly closed-loop development and debugging.
